Actually, Hal, it depends on *how* different you want it. :-)

They have engineered Drosophila with legs growing out of the head and I believe with extra sets of wings. It simply involves adding putting a gene that makes and "X" and under the regulation of the "Y" region control element, i.e.

	if (I_Am_In_Region_Y)

If it looks like something you already grow, you could probably assemble them in a fairly ad hoc fasion.
